FLUSI-I-TANK MECHANISM.

Application filed. July 15, 1925. Serial No. 43,709.

This invention relates tomechanism for flushing tanks and refers moreparticularly to the mechanism for operating a closet tank flush-valve.

The principal object of this invention is to provide rectilinearlymovable cam means for operating the flush-valve of a watercloset tank.Another object of the invention is to provide rectilinearly movable cammeans in combination with a sliding pushpin for operating theflush-valve of a watercloset tank, 1 1

Other objects of the invention are mentioned and described herein.

The preferred embodimentof this invention is illustrated intheaccompanying drawing in which Figure 1 is a vertical section throughthe flushing tank showing the general arrangement of the parts; Fig. 2is a cross-section taken on line 22 of Fig. 1; Fig. 3 is a similar viewtaken at right angles; and Fig. 4 is a perspective of the pushpinbearing element.

Similarly numerals of reference indicate like parts throughout theseveral views on the drawing.

Referring to the details of the drawing the numeral 1 indicates afragment of a flushing tank provided with the usual discharge 2, thelatter being controlled by a float-valve 3 which has the usual verticalvalve stem l operatively connected with the link 5, the latter beingconnected with the outer end of the flush-valve lever 6.

The valve operating lever 6 is carried by the arm 7 projecting from thebearing element or plug 8, being pivotally mounted thereon at 9intermediate its extremities to rock in a vertical plane within theflushtank. The bearing plug 8 has a polygonal portion 10 arranged withina polygonal opening 11 formed in the tank wall to prevent rotation ofsaid bearing element. A nut 12 may be screw threaded upon and about theouter end 13 of the plug 8 to maintain its juxtaposition in the wallopening 11. The bearing plug 8 is provided with a cylindrical bore 14extending axially therethrough at substantially right angles to thevertical plane of movement of the lever 6, a push-pin 15 being slidablyarranged in said bore. The pin 15 may carry a knob 16 at its outer endto facilitate manual actuation thereof, and the inner end of said pin isprovided with a conical cam element 17 rigidly mounted thereon andadapted to push-pinq15. as an abutment or stop element to limit the rockthe lever 6 when-said push-pin'is. actuated. i r v The point of theconical cam 17, is prefer-- ably elongated at '18to overlie theshort end19 of the lever 6' when the push-pinis normallyretracted by acoiltensionsprinm 20 which bears against the outer end ofthe plug '8'and against the knob 16, the butt end of said cam element normallyengaging the inner face of the-plug 8 and thereby limiting theretractive movement of the The cam point 18 also serves retractiverocking movement of the lever 6 when the pin 15 is retracted bythespring 20. Obviously, forward sliding movement of the push-pin 15will cause the conical cam 17 to move in a rectilinear path across theend of the lever section 19', whereby the latter is rocked and the,valvefi unseated. To prevent later.al1distor.tionor. vmovement of theleveru6 when the cam 1'71 is thrustacross, lever section 19 ,anabutment,21 is provided, said abutment being preferably formed as an extension ofthe arm 7 and having its face in permanent engagement with the face ofthe lever 6.

I claim 1. In lever mechanism for closet-tanks,

jacent said lever and movable transversely thereof and across the same.7

2. In lever mechanism for closet-tanks,

the combination of a fixed bearing element mounted in the flush-tankwall, an arm carried by said bearing element, a flush-valve leverpivotally mounted upon said bearing element arm and oscillative in avertical,

plane, a push-pin slidably mounted in said fixed bearing and movabletransversely of the plane of movement of said flush-valve lever, a camcarried by said push-pin, whereby sliding movement of said push-pin willcause rocking movement of said lever, and an extension of said cam whichoverlies the flush-valve lever to limit the retractive retracted.

Within the tank, cam means associated With said bearing element andmovable in a rectilinear path to cause rocking movement of said lever,and means to prevent lateral distortion or movement of said lever uponactuation of said cam'means.

4. 1n lever mechanism for closet tanks, the combination with a fixedbearing element mounted in a flush-tank Wall, said bearing element beingprovided with an arm,

of a pivotally mounted flush-valve lever arranged Within thetank andsupported by said arm of said bearing element, cam means associatedwithsaid bearing element and movable in a rectilinear path to cause rock-111g movement of said lever, and means carried bysaid bearing elementarmto prevent distortion or lateral movement of said lever upon.actuation of said 'cam means.

5 Inlever mechanism for closet tanks,

the combination of a fixed bearing element mounted in the flush-tankWall, an arm carried by said bearing element, a flush-valve leverpivotally mounted upon said bearing element arm, a push-pin slidablymounted in said bearing element and movable in a rectilinear. pathtransversely of the plane of rocking movement of sa d lever, a conicalcam carried by said push-pin, and an extension for said cam Whichoverlies the flush-valve lever to limit the retractive movement of thelatter.

6. In a closet tank, a flush valve, a bearing element mounted in theWall of the tank,

a push-pin slidably mounted in said bearing element and extending to thetank exterior,

7. In lever mechanism for closet tanks,

the combination of a fixed bearing element mounted in the flush-tankWall, said bearing element being providedwith asubstantially horizontalbore open at both ends thereof,

an arm carried by said bearing element.

Within said tank, a flush-valve lever pivotally mounted upon saidbearing; element arm, a push-pin slidably mounted in said bearingelement bore and movable transversely of the plane of rocking movementof said lever, and a separate part conical cam carried by said push-pinat its innerend and adapted to engage and rock said flushvalve leverWhen said push-pin is slidably actuated.
